　　 "Adult, everything is ready, is it time to start ironmaking now?" Xu Sheng came to Lin Ze with a look of excitement.

　　 This time, Xu Sheng is arranging things. Once it is done, it is definitely a great thing.

　　 "Well, let's start!" Lin Ze nodded indifferently.

　　After receiving Lin Ze's order, Xu Sheng immediately ordered the start of iron making.

　　 is very chunky, Xia Ming has prepared it early, and the blacksmith leader Hu Yan, who has tried several times in the plane seed world, stands by the kiln, directing the workers and apprentices around him to run up and down.

　　Hu Yan is actually a master-level refiner. This time he was discharged by Lin Ze to take charge of the steel plant.

　　 This steel plant is a very important position for Lin Ze in the future. Here, of course, Lin Ze must arrange a talented person who understands the ironmaking technology and is extremely loyal and capable.

　　 Otherwise, such an important place will be given to others, even if Lin Ze is at ease, Wang Ming will not be at ease.

　　 Therefore, Hu Yan was sent out by Lin Ze.

"Li San over there, what are you doing with such a thick stick? Does it burn through? Saw it all and saw it all! Don't make it into such a large section, but subdivide it so that it will burn in a moment. better."

　　 "Hey, over there, put the twigs underneath, and then sprinkle some pulverized coal on top, so that it will burn well, and the pieces that are burnt will be transparent!"

　　Hu Yan deserves to be a specialized talent, and he has practiced several times in the plane-seed world. Therefore, the command is extremely appropriate. Although there are some small flaws, but the flaws are not concealed, most of them are still good.

　　With Hu Yan's order and command, the wood was moved into the kiln, and the workers immediately set fire to the fire mouth on the first floor.

　　 ‘Boom! ! 'The sound of the wood in the second floor kiln was burnt, and the moisture in the wood began to evaporate continuously, mixed with some other volatiles, forming a clear gray cold smoke, because the temperature was not high, it came out of the chimney After going out, it does not go up, but spreads out flat along the ground. Later, as the temperature gradually increased, the coal on the first floor was burned out, and the wood in the kiln on the second floor began to oxidize and heat itself. If you have a pair of perspective eyes, you can clearly see that the wood material has undergone thermal decomposition reaction, and its composition begins to occur. Changes.

　　 Among them, unstable components, such as decomposition of hemicellulose, generate carbon dioxide, carbon monoxide, and a small amount of acetic acid.

The wood itself decomposes and heats up, pushing the temperature in the kiln to the highest point. At present, it is about 400 degrees Celsius. Under such high temperatures, the wooden materials in the earth kiln are rapidly thermally decomposed, and the wood surface has a viscous oily stream. Out, that is a lot of acetic acid, methanol and wood tar produced by the reaction.

　　 If you look closely, you will find that there will be a bubble from time to time. This is a combustible gas such as methane and ethylene. They burn slowly in an oxygen-deficient environment in the furnace, releasing heat and maintaining the temperature of the kiln inside.

The workers can actually leave here to do other things at this time. Anyway, everything in the kiln is normal now. Whether it is the burning of the wood inside or the smoke from the outside, it is in line with the design. There is no problem, so the wood inside will react slowly without human intervention.

　　 However, this is the first refining, so everyone did not leave, just stayed on the side, watching, wanting to enjoy the joy of success for the first time.

However, this time must take quite a long time, because, depending on the humidity and thickness of the wood inside, it takes 12-24 hours to prepare for the kiln, so most of the waiting people finally leave for rest. The same is true for Lin Ze, who will wait until the end to come again.

　　 Those other people have the same thought, they will come again when Lin Ze comes again.

　　 The time passed quickly, and the next day came soon.

At this time, the workers and apprentices under the command of Hu Yan blocked the chimney at the top of the kiln. The chimney was originally designed to be very small. The kiln reacted in a very oxygen-deficient environment. This was because the oxygen was completely blocked. Input, therefore, the oxidation reaction in the kiln stops slowly, and the kiln temperature gradually becomes lower.

　　 If it is urgent, you can actually open the kiln earlier and then water the burnt charcoal; if it is not urgent, you can wait for it to cool naturally in the kiln to below one hundred degrees Celsius, and then open the kiln.

　　Just like this, the charcoal that can be used for smelting high-quality iron is burned in this way. It has extremely high carbon content, low content of impurities such as phosphorus and sulfur, strong reducibility, and has a porous structure, which is better than coke in blast furnace ironmaking.

After finishing this refining, on the open ground, there are already four or five feet high in the east, a lot of black charcoal; a high height of three feet in the west, and a bunch of tan magnets with stars and spots. Ore, these are crushed qualified iron ore.

　　Obviously, the first ironmaking has only come to the point until now.

Hu Yan did not delay, he quickly went on to the next step. Under his auspices, a belly with a wide belly and a narrowed neck gradually looked a bit like a blast furnace at the ///de//zhen// vase in this steel factory Not far from those animal power institutions, the foundation of the sedimentary rock platform was erected.

　　 That’s right, it was indeed built by Hu Yan. Lin Ze only proposed some amendments according to the modern iron smelting process.

　　 Lin Ze is not an authoritarian person or a scientific genius. He always has an envelope in his heart, and special things need to be handed over to special people.

　　On the iron making, Lin Ze only knows some fur, which is far inferior to those of Hu Yan. Therefore, these professional matters should be left to Hu Yan and other professionals to do well, so as not to make mistakes or reduce errors.

　　 Seriously, if any of the traversers returned to ancient times, he wanted to "invent" blast furnace ironmaking to get the first pot of gold, then he would eventually be alive and dead, because the blast furnace has been popularized since ancient times.

For example, during the Yuanfeng period of the Song Dynasty, the military bureau of the imperial court erected blast furnaces on both sides of the Bianhe River. The scale was not small. Too.

　　According to historical records, at that time the red light of ironmaking reflected the sun, day and night. During the peak period of production, the annual steel production in the area around Bianjing alone reached 150,000 tons;

　　 This is 150,000 tons. You must know that the future sunless empire will only reach 76,000 tons of steel annual output after a full 700 years. At that time, it has already begun the early industrial revolution.

　　 The entire Song Dynasty period, including the Northern Song Dynasty and the Southern Song Dynasty, has a small territory, including the adverse factors of production damage during the war. Even so, it can actually reach an average annual output of 35,000 to 70,000 tons of steel!

　　Especially in the later Southern Song Dynasty, the iron and steel industry in the south was extremely developed, and some large blast furnaces could smelt tens of thousands of kilograms of pig iron at a time (just pig iron, not steel).

　　 Speaking of things like this, many people would not believe it, or even wonder if it is true. After all, it was thousands of years ago. How could such a ‘advanced’ ironmaking technology be.

　　 But this is true, because in fact the construction of the blast furnace is not complicated, it is like a special thing (not a typo) at the end of the 1950s of the last century, calling on the people of the whole country ///// refining // steel.

　　 In this special event, some elementary school students, villagers of production teams, salespersons of non-staple food shops, and illiterates all formed iron-making teams to build blast furnaces to make steel and iron.

　　 The technical level of those blast furnaces is about the same as in ancient times. It is theoretically possible to make iron, but the technical mastery is not enough, so most of them are lost.

　　 But even then, these are also blast furnace ironmaking, the quality of the iron and steel produced is not good, most of them are wasteful, but always steel is not.

　　 It was already possible for the era to pursue only steel production.

　　Hu Yan is not mixing these days, he also made some other preparations.

First of all, he found suitable high-alumina clay around Huangsha Town according to the information provided by Lin Ze. This thing has high alumina content. After grinding, limestone is calcined, which is refractory cement; directly pressed into bricks, at 1300 degrees It can be fired into refractory bricks at high temperature.

In fact, for the small blast furnace designed in this era, it is not a big problem to use clay directly to build it~www.wuxiaspot.com~ or to use red bricks. The most is the poor quality. The replacement needs to be diligent and will not be true. The key to ironmaking is that Hu Yan, as a master-level smelter, has extremely strict quality requirements. Hu Yan hopes to do his best from the beginning and increase its service life.

Therefore, according to some information provided by Lin Ze, Hu Yan found these special high-alumina clay surfaces, and used them in the lining of the blast furnace, and also used the means of the refiner to refine the use of the modern steel-making furnace. Advanced refractories.

　　 The blast furnace that was finally refined really has the example of a modern blast furnace, even in certain qualities, it comes stronger.

　　After all, Hu Yan is a master-level refining master. The means of a refining master is not something that ordinary people can imagine.

　　 The problem of the blast furnace was solved, and the remaining blowers were also a big problem.

When modern blast furnaces are refining, they use special fans. In this case, the horsepower is strong and the wind speed is stable. It is very good for steel making. However, here is the mainland of China, where is the electricity, so where is the electricity Fans and the like.

Even if it is in the hands of a refiner like Hu Yan, most of the refining is still using wind-control or magical instruments, which not only consumes the refiner’s true energy, but also requires considerable energy. Compared to modern fans, it is indeed cumbersome and a lot of trouble.
